AOCORDION,

SPECIFICATION forming part of Letters Patent No. 370,217, dated September 20, 1887.

Application filed March 2B, 1887. Serial No. 232,776. (No model.)

To all whom it may concern'.-

Be it known that I, JOHN F. STRATTON, of the city, county, and State' of New York, have invented certain new and usef'ul Improvements in Accordions, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved accordion, in which the same note or tone can be sounded by both pushing and drawing the bellows.

The invention consists of an eXtra set of keys, key-valves, reeds, and reed-valves added will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a tenkeyed accordion provided with my improvement. Fig. 2 is a plan view of part of the same on the line x x of Fig. l. Fig. 3 is a diagram of the arrangement of the reeds, and Fig. etshows the notes which can be played with my improved accordion in pushing and drawing. Fig. 5 is a sectional elevation of the reeds and valves on the line y y of Fig. 2.

Heretofore accordions have been provided with oneor two sets ofmelody-keys,key-valves, reed-valves, and reeds, and in the latter case one set was tuned to a different key than the other, so that a performer could play a certain melody in either of the two keys to which the the keys of the regular set, thus permitting the performer to play any passing note of the scale, which passing notes are not included in the regular set.

In the drawings is illustrated a ten-keyed accordion; but my improvement can also be easily adapted to asix or eight keyed accordion without changing the principle of my invention.Y

The accordion a is provided with the melodykey board b, having the regular set of keys c operating the key-valves c of the regular set of keys dto produce the tones C E G, C E G, C E G, Sie., of the scale in which the reeds are tuned when pushing the bellows, and in drawing the bellows the tones D F A B, D F A B, die., are sounded by the said reeds d. To this set of keys o, keyvalves c', and reeds d, I add an extra set of melody-keys, e, operating the key-valves c of the reeds f, which produce, when pushing the bellows, the tones D F A B, D F A B, &c., and in drawing the bellows the tones C E G, C E G, (l E G, the., are sounded by the said reeds f.

It will be seen that the additional set ol reeds, when played successively and at the same time pushing the bellows, produce the same sounds as when playing the regular set of reeds d and drawing the bellows, and vice versa. The tones D F A B, D F A B, when pushing the bellows, and the tones C E G, C E G, die., when drawing the bellows,are called passing notes or tones, and cannot be played on the ordinary accordion when playing the regular reeds d, as the performer cannot push and draw the bellows at the same time. The extra set of keys e are arranged midway between the regular set of keys c, so

as to permit the performer to finger very conveniently. The other parts of the accordion are the same as in ordinary accordions.

It will be seen that the additional set of reeds can only be used for playing passing notes in a melody; but a melody in itself can;1 not be played by the said reeds, and must be played in connection with the regular set of reeds to produce a melody. It will also be seen that the regular accompaniment of the bass-reeds would not fit the additional set of melody-reeds to produce harmonious sounds, and the .said additional set of melody/reeds cannot be used as an accompaniment to thc regular set of melody-reeds.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

IOO

dition-al set of melody-keys, key-valves, and corresponding reed-valves and reeds tuned in such a manner as to produce, when played successively while drawing the bellows, the same tones as the said regular set of melodyreeds produces when played while pushing` the bellows, substantially as shown and de- 2c scribed.

JOHN F. STRATTON.
